Bob, if your only realistic choice is between the Dewalt 788 and the Delta 60-694, then I would suggest that you buy the Dewalt 788. Both saws are very similar in the way that they are built and operate, but, the Delta saw is inferior to the Dewalt saw. It is built using cheaper parts, and there's a couple of other things that are different about the saws, I just don't recall what they were. I did a very intense bit of research on these two saws, because it was when I needed a new saw. The Delta was a new saw at the time, and all of the information I found on the net about them reported that they were cheaper made. The reason for making the Delta cheaper than the Dewalt, was to be able to offer a saw at a cheaper price. They were meant to be a mid range priced saws, that the manufacturer hoped would sell in place of the other after market saws. This was reports from reputable people and magazines, there was a fair amount of info out there at that time. That's why I looked into these two saws, I thought that I might buy the new Delta. But after reading everything I could find on the two saws, I decided to buy an EX21. The Dewalt would have been my second choice, but, the tilting head on the EX is what won me over.

P.S. I don't know where you got the numbers from, but, there is no 150% difference in price between the two saws. If I were to use the prices you quoted on the two saws, then there's only a 44% difference in price between the two. Which is what it should be, as they are cheaper made saws.
